UNITED STATES PATENT OFFICE.

l EDWARD BURNS, OF BROAD FORD, PENNSYLVANIA.

COKE-OVEN.

SPECIFICATION forming part of Letters Patent No. 232,389, dated September 21, 1880. Application led February 12, 18E0.

Tocll whom it may concern:

Be it known that I, EDWARD BURNS, of

of Pennsylvania, have invented a certain new and useful Improvement in Coke-Ovens, of which the following is a specification.

My invention relates to that class of ovens or furnaces in which the volatile matters of coal are expelled, leaving the coke or carbonaceous portion.

The construction of a coke-oven embodying my improvements will first be described, and the invention. designated in the claim.

In the drawings hereto annexed, Figure l is a front eleva-tion of the oven. Fig. 2 is a vertical transverse section taken through line x m, seen in Fig. l. Fig. 3 is a plan or top view of the oven.

The letter A designates the front wall 5 B,

the smoke-stack; C, the dome-shaped arch ot' the oven; d, a hearth, preferably circular in shape; c, the charging-hole in the top, provided with a suitable cover; and f, adoor in the front wall for withdrawing the coke. The several parts thus far named are of ordinary construction.

. On the exterior sides of the base ofthe oven, commencing at the front'wall, an air-Hue, h, extends to the rear side, forming, as seen in Fig. 3, a half-ring. These lines connect with openings h in the walls, of which one is on each side of the door. The other end of the air-dues connect at the rea-r side with a ringshaped smoke-Hue, fi, which, in the present in stance, entirely surrounds the dome of the oven on a higher plane than thc two air-fines. The inlet to the smoke-Hue from the oven is shown at n in Figs. 2 and 3, and the ends ot' the ring smoke-tine, where they discharge into the smoke-stack, are shown at g, Fig. 3.

It will be seen the iiame from the gases ot the charring coal will pass ont of the oven at n and turn in both directions to the smokestack. At r (shown in dotted lines in Figs. 2 and 3) the half-ring air-dues connect with the hillside, so as to render it easy for the coal to be hauled to the charging-hole.

The construction herein described has been demonstrated by practical operation to be well adapted Jfor producing good coke. It is convenient for operation, and when being charged there is no escape of iiame to annoy the oper ator.

I am aware that it is not new to mingle air and the products of distillation in the walls of a coke-furnace by means ot' pipes or ilues passing around or through the walls of the oven, and l do not claim, broadly, means for accomplishing that result 5 but myinvention relates to a certain arrangement of smoke and air lues, which effect the aforesaid mingling at a certain point.

Having described my invention, I claim and desire to secure by Letters Patent of t-he United States- In a eoking-oven, the combination of the ringshaped smoke-due "J, extending horizontally around the oven, and at the rear side connected with its interior by the flame-aperture n, and the two 4air-supply flues h, each having its inlet at the front wall and extending around the oven below the smoke-flue, and at the rear having a connection, r, with the ring-shaped smoketlue,but upon opposite sides of the flame-aperture, as set forth.

EDWARD BURNS.
